Proceedings of International Symposium on East-West Medicine, Seoul. 244-254, 1999.-Obesity can be defined as a metabolic disease due to an increased state of fat tissues caused by an imbalance of calorie intake and use. Recently, in Korea by improvement and westernization of food intake, along with decrease in exercise activities, the prevalence of obesity has increased greatly. Our objectives were to study stability and effects of decrease in body fat by administering red ginseng compound preparation (known to have body fat decreasing effects in laboratory animals) to obesity patients on low calorie diets. Changes in weight and body fat were measured while carrying out calorie-restricted diets on patients for 4 weeks, then administering red ginseng compound preparation for another 4 weeks. The patients were 20 people whose BMI were 25kg/㎡ or over and whose percent body fat was also 30% or over when tested by bioelectrical conductivity. 1. Changes in weight were from 70.04kg(base line) to 67.43kg(after taking red ginseng compound preparation). 2. In similar sense, BMI decreased from 27.12kg/㎡(base line) to 26.56kg/㎡(after dieting), and further to 26.01kg/㎡ (after taking red ginseng compound preparation). The BMI seemed to decrease significantly compared to the baseline after the use of red ginseng compound. 3. Waist hip ratio was changed from 0.8858(base line) to 0.8728, but it was statistically insignificant. 4. The percent body fat was 35,16%(base line), 33.87%(after dieting), and 31.68%(after taking red ginseng compound preparation). 5. Complete blood cell count and blood chemisrty remained unaffected by the administration. 6. In concern to endocrinologic studies, T3 decreased from 118.7 to 98.2ng/dL, and T4 increased from 8.8 to 9.2㎕/ dL. Epinephrine showed a tendency to decreased from 0.27 to 0.25 ng/mL, and norepinephrine increased from 0.39 to 0.44ng/mL. 7. Leptin was not changed. 8. Some patients complained adverse effects; constipation(5 patients, may be due to diet therapy), fatigue (2 patients), pruritus(2 patients), flushing(s patients), dizziness(3 patients) and epigastric discomfort(2 patients). However their symptoms were mild, so medication did not stopped. In conclusion, loss of weight without significant side effects was observed during low calorie diet and red ginseng compound preparation administration. This is thought to be in relation to sympathetic nerve system rather than adrenal gland. Also, further long0term studies should be required, since the observed results were based on short-term changes in weight.

The Computer Algebra Systems in Mathematics Education : A Review of Recent Research

Kwon, Oh-Nam,Shin, Eun-Ju,Shon, Bo-Kyung 이화여자대학교 교과교육연구소 2001 East west education Vol.18 No.-

This study examines the potential role for Computer Algebra Systems(CAS) in such an educational context, particularly their potential to get students more engaged in the learning of mathematics as well as to reduce the "strangle hold" of prerequisite algebraic skills, in courses such as functions, introductory calculus. What is the present status of and near-future outlook for computer algebra in Korean secondary schools? The answer that arises from this review of available fact is: bright with promise, but still dim. Several recent developments have set the stage for an acceleration in the dissemination rate for CAS to high schools. However, this review of some past and present conditions indicates that many years will pass before computer algebra is impacting high school mathematics as much as hand-held calculators are doing now.

이 연구는 전남 신안군 상태도에 위치한 상서고분군 축조에 사용된 석재들에 대한 암석학적 특성과 채석 등 유통과정에 대해 고찰하고자 하였다. 고분 축조에 사용된 석재들에 대한 암석학적 특성 연구는 외관적 관찰에 의한 암석기재적 연구와 편광현미경 하에서 암석의 광물조성과 조직특성에 대한 연구 및 암석의 주성분 함량조성을 통한 지구화학적 연구를 수행하였다. 이 연구들과 함께 주변지질들과 관련하여 고분석재들의 채석과 이송 등에 대한 연구도 병행하였다. 고대로부터 신안군 일대는 한국-중국-일본을 연결하는 고대 해상교통로에 중요한 위치를 점하는 것으로 알려져 고분 축조에 사용되었던 석재 연구는 고대 해양사 측면에서 의미를 지닌다고 할 수 있다. 기재적 관찰에서 석재들은 중성암맥 기원인 안산반암을 제외하고는 대부분이 응회암류에 해당한다. 이들은 라필리응회암과 세립질 응회암으로 구분되는데 대부분 세립질 응회암에 속한다. 응회암 구성입자들은 각상에서 초각상이고 분급도는 불량하다. 세립질 응회암들은 매우 치밀한 조직을 보유하고 특히 라필리응회암의 불규칙한 이탈흔들은 타포니(tafoni)와 관련될 가능성이 있다. 응회암의 입자들은 사장석편과 암편 등이 주를 이루며 크기 범위가 광범위하다. 사장석들은 알바이트 쌍정이 잘 나타나고 격자쌍정을 이루는 미사장석들도 출현한다. 응회암의 치밀한 조직은 부분적으로 속성작용과 관련되는 것으로 여겨지며 다양한 풍화정도를 보인다. 또한, 미세한 석영맥들이 응회암들을 종횡으로 관통하고 있다. 상기한 상서고분군 석재들에 대한 주성분 원소 함량에 대한 지구화학적 연구에 의하면, 이들 응회암은 화산암류 관점에서 산성암계열에 근접한 중성암 계열 및 산성암계열에 해당시킬 수 있다. 이러한 함량분포 특성 상, 이 응회암들은 두 가지 군으로 나눌 수 있다. 그리고 TAS(total alakali vs silica) 분류에서 이 응회암들은 저알칼리암 계열에 도시된다. 고분축조에 사용된 응회암들은 주변의 암석과 매우 유사하며 석재들 자체도 광물조상과 조직특성에서 서로 유사정도가 높다. 일반적으로 응회암들은 판상특성, 가공의 용이성 및 상대적인 견고성으로 고분과 건축 등에 많이 이용되어 왔다. 이러한 결과들을 기반으로 고분축조에 사용된 응회암들은 산성암계열에 근접한 중성암계열 및 산성암계열 기원을 가지며 주변 암석에서 채석·이송된 것으로 추정된다. This study considers on petrological characteristics and distribution to building stones of Sangseo tumuli in Santae Island, Shin-an, Jeonnam. The petrological study on the stones includes visually petrographical descriptions, textural study by polarized microscope and geochemical analysis. Along with the study, distribution routes of the stones were traced based on the regional geology of the island. Since ancient times, the study area is important as a base on international maritime traffic route. Therefore, studies on the tumuli are meaningful for ancient maritime history. In visual observation, above building stones are of tuffs except for an andesitic porphyry considered as intermediate dyke. The tuffs are assigned to lapilli and fine ones. Their grains are poorly sorted and angular to very angular in roundness. In particular, the fine tuffs show very dense textures and take up the most part of the building stones. In addition, the stones have irregularly removed depressions inferred as the linkage to tafoni, in lapilli tuffs particularly. The tuffs are mainly of plagioclases laths, rock fragments and matrices and ranges widely in grain size. The plagioclases show mostly unambiguous albite twin. And, microcline crystals are observed in the tuffs too. Matrices in the tuffs are considerably dense and weathered. Dense texture in the rocks are related to diagenesis in part. In addition, thin quartz veins irregularly intruded the rocks vertically and horizontally. According to the geochemical analysis of building stones of above tumuli, the stones might be intermediate rock series near acidic rock ones and acidic rock ones in the correspondence of volcanics. Therefore, the tuffs probably grouped as two types and are assigned to subalkaline rock series by TAS diagram. Most the building stones mutually resemble in visual and textural characteristics. Tuffs are generally platy, easy in use and relatively hard. In addition, rocks very similar to the building stones are widely distributed in surrounding area. Synthesizing above results, it is considered that tuffs used in tumuli building are corresponded to intermediate rock series near acidic rock ones and acidic rock, and got from surrounding rocks.

The present study was carried out to find the attempt that exhibits the Lest record during long jump competition. The subjects of this study were 72(male=40, female=32.) long jump athletes who passed elimination in national track and field events, These subjects practiced six long jump during their competition Therefore, total trials of long jump were 432. Arid these records were recognized as official records by Korea Amateur Athletic Federation. The results were as follows; First, total Repeated ANOVAs revealed that there was no significant trial difference, but separate Repeated ANOVAs revealed that there was significant trial difference in gender records. Second, there was significant trial difference in male records, and post-hoc revealed that the record of 5 trial was the highest. Third, there was no significant trial difference in female records. From these results, I suggest that it is important for long jump athletes and their coaches involved in competition to be familiar with the variety of mechanism which can be leaded fatigue, and that it is desirable to exhibit the Lest competition record during elimination period.

We develop a practical equalization algorithm which can be used to improve data transmission rate and transmission error rate. The algorithm combines a blind method and a training method to estimate a communication channel. Since we use a blind method after training method processed, our algorithm improve data transmission rate and transmission error rate. For practical implmentation, we suggest an adaptive algorithm which can be used in real time applications such as a digital communication system. We demonstrate that our algorithm can reduce transmission error rate for an indoor wireless communication channel model through a simulation.

A study was conducted on the effect f creatine loading on persistent exercise and outcome in sprint which was performed immediately after such exercise and subjects of this study were 12 cycle load athletes. Persistent exercise for the purpose of experiment was carried out for 2 hours and 30 minutes. Then it was continued until the condition of tiredness and exhaustion was reaching with showing density of lactate in blood of 4mmol/ℓand then immediately thereafter for 10 seconds 5 sets maximum sprint were carried out. The subject athletes carried out C Performance which featured absorption of placebo liquid during the exercise involving creatine loading prior to experiment exercise, CC Performance featuring absorption of creatine liquid during the exercise involving creatine loading and P Performance featuring absorption of placebo liquid during the exercise without creatine loading-thus totally 3 Performances were carried out. Comparing with P Performance C Performance showed significant improvement in all the 5 sets in terms of peak power and average power for maximum sprint. On the other hand in CC Performance it was same as P Performance. Creatine loading and creatine absorption liquid did not have any effect on duration of persisting exercise until reaching to fatigue and exhaustion. From the result of this study it could be observed that creatine loading improved maximum sprint ability within a short period of time after persistent exercise leading to fatigue and exhaustion However such effect declined when creatine liquid was absorbed during the exercise.
